We compared Microsoft Defender for Cloud Apps (MDA) and Zscaler Internet Access based on our users’ reviews in five categories. After reading the collected data, you can find our conclusion below.
Comparison Results: Microsoft Defender for Cloud Apps is the preferred option over Zscaler Internet Access because of its comprehensive features, integration with other Microsoft solutions, and personalized rules and policies for cloud traffic control. Zscaler Internet Access has a cloud-native proxy architecture and advanced threat protection but has faced issues with reporting functionality, pricing, and technical support according to users.
"The protection offered by the product is the most valuable feature. It detects vulnerabilities or traps on our users' phones and then prompts them to clean up their devices. Tools we used previously would only discover, which required us to gather information on the backend, so Lookout is a welcome upgrade."
"The solution is stable."
"The most valuable features are the antivirus as a whole, the anti-malware, and all of the protection features that scan our enterprise devices."
"On the outside, the main differentiation is because Lookout ingest. They have ingested basically all of the apps for the last ten years and all the versions of all the apps, and we have that in a corporate database that allows us to do very large-scale machine learning and analysis on that data set. That's not something that any of the competitors really have the capability to do because they don't have access to the data set. A lot of the apps you can no longer get them because that version of the app is five or six years old, and it just doesn't exist anywhere anymore, except within our infrastructure. So, the ability to have that very rich dataset and learn from that dataset is a real differentiator."
"Better logging allows us to find problems and take appropriate steps to lock them out."
"The product’s most valuable feature is SQL database."
"Threat detection is its key feature, and that's why we use this tool. It gives an alert if a PC is attacked or there is any kind of anomaly, such as there is a spike in sending emails or we see an unauthorized website being accessed. So, it keeps us on our toes. We get to know that there is something wrong, and we can isolate the user and find any issues with it. So, threat detection is very robust in this tool."
"Defender helps us control which applications are being used and gain more security insight into remote and hybrid users based on user identity and log in location. You can also integrate Defender for Cloud Apps with Defender for Endpoint to extend its capabilities."
"I like the alert policies because they are quite robust. It has some built-in templates that we can easily pick up. One of them is the alert for mass downloads, when a particular user is running a massive download on your SharePoint site."
"The feature that helps us in detecting the sensitive information being shared has been very useful. In addition, the feature that allows MCAS to apply policies with SharePoint, Teams, and OneDrive is being used predominantly."
"The most valuable feature is the alerting system."
"The most valuable feature of this solution is its monitoring."
"The most valuable feature is the ability to drop packets."
"The initial setup is very straightforward."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"SSL inspection is a valuable feature."
"Tech support is good."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"Zscaler Internet Access's best feature is the granular policy controls."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"From the analysis that we've done, they do seem to be maybe a step behind in trying to enter the market with a new solution. But when they do pick up, they do come out with some good products."
"The stability depends on the service from where you access it. Because sometimes, the place you are in, you have Gateway. You don't have Gateway. The gateway is overutilized. At the end, you need to go through their gateways. And this is the key point here. You have a tracking point. If it's not well orchestrated, and it scales up as you add more to the existing team, you will suffer"
"We just submitted an enhancement request reflecting the main area we want to see improvement in; the APIs. Currently, we're able to build dashboards, but it's somewhat backward because we use our MDM API to create them. Lookout should provide API to customers so we can query our data and use it in our cloud, and this is the only outstanding area for improvement with the product right now."
"Lookout was moving into the SSE space. And so their work on SecureWeb Gateway and SD-WAN is still sort of evolving."
"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."
"They need to improve the attack surface reduction (ASR) rules. In the latest version, you can implement ASR rules, which are quite useful, but you have to enable those because if they're not enabled, they flag false positives. In the Defender portal, it logs a block for WMI processes and PowerShell. Apparently, it's because ASR rules are not configured. So, you generally have to enable them to exclude, for example, WMI queries or PowerShell because they have a habit of blocking your security scanners. It's a bit weird that they have to be enabled to be configured, and it's not the other way around."
"Microsoft Defender for Cloud Apps' initial setup was quite technical but we were prepared. The time of the implementation depends on the job and how many users are being set up."
"They should continue integration with all other Microsoft security-related products. The integration with all the other products is still ongoing."
"This service would be better if it had a separate license, only for this service, that could be used to track usage."
"Microsoft Defender for Cloud Apps’s technical support services needs improvement."
"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."
"Sometimes, we'll get false positive alarms. For example, when a SharePoint path has no file sharing, but there is an external user, it will trigger an alarm that the file has been shared with an external user... the alerting mechanism should be more precise when giving you an alert about what activity has been done with the file..."
"They should enhance the audit reporting feature."
"Technical support could be better."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
